This little monster is the Skoda-built 305mm mortar produced for the Czech army in the interwar years. A total of 17 such mortars were in service when Czechoslovakia was occupied by the Germans, who immediately pressed the 305 mm into service under the designation 30.5 cm Morser. An additional six of the mortars were captured in Yugoslavia and also saw service on the Eastern Front under the designation 638(j). Photo taken in 1938.
